Resumen:
The covariant propagator of a fermion with intrinsic magnetic moment interacting with a uniformexternal magnetic field is presented for finite temperature and baryonic density. The case of a scalar bosonis also considered. The final expressions are given in terms of a four-dimensional momentumrepresentation. These results, which take account of the full effect of the magnetic field, are used toevaluate the modification of the pion mass at zero temperature as a function of the density and the magneticintensity. For this purpose a self-consistent calculation, including one- and two-pion vertices, is employed.
